Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562282, here are decompositions:

19 + 31562263 = 31562282
163 + 31562119 = 31562282
229 + 31562053 = 31562282
313 + 31561969 = 31562282
379 + 31561903 = 31562282
571 + 31561711 = 31562282
613 + 31561669 = 31562282
709 + 31561573 = 31562282

Showing the first eight; more decompositions exist.
